BOILEBwFLUE-CLEANEB SYSTEM.

Specification of Letters Patent.

Patented Oct. 15,1912.

To all it may concern:

Be it known that I, JAMES Moonn, a citizen of the United States, and residing at Boston; in the county of Suffolk and State of Massachusettsyhave invented certain new and useful Improvements in Boiler- Flue- Cleaner Systems, of which the following is a specification.

This invention relates to certain new and useful improvements in boiler flue cleaner systems, and relates more p'articularl t.o that type of flue cleaners in which a 111d, as steam, is employed as a cleaning agent for removing soot from the fines and preventing an accumulation of soot on the fiues.

The resent invention is an improvement upon me cleaners of the type shown, described, and claimed in Letters Patent 705,912, granted July 29, 1902, to William Eichelberger for soot cleaners for boilers; Letters Patent #801,858, Oct. 17, 1905, soot cleaners for boilers, to the same party,

and Letters Patent #984,919, Feb. 21,

1911, boiler flue cleaner systems, granted to De Los E. Hibner. v

The present invention relates to improvements in the general type of flue cleaner disclosed in the above noted patents, and has for its main object to provide a flue cleaner of this type in which the distributing pipes for the cleaning agent are rotatablymounted, and which are provided each with a plurality of nozzles having outlet nipples that are projected on a line so as to discharge the cleaning agent at an oblique angle to the axis of the tube, and which outlet nozzles are so disposed with relation to the rows of tubes comprising a battery of tubes or boiler, that as the distributing pipe is revolved, the angle of projection'is altered whereby the entire surface of the tubes is efl ectually cleaned by the steam or other fluid cleaning agent.

It is also an object of the present invention to provide novel, simple, and efl'ective means for rotating the distributing pipes and to permit such operation of the distributing pipes being readily accomplished at a point some distance from the pipe or pipes, that is, to provide for the easy rotation of the pipes from the bottom of the boiler setting, in cases where the distributing pipes are arranged at a point materially above the base of such boiler setting.

With the above and other objects in view, the invention consists of the novel construction, combination, and arrangement of parts as will be hereinafter more particularly described, and then claimed, and in describing the invention in detail, reference will be had to the accompanying drawings illustrating a preferred embodiment of the invention, and wherein like numerals-of reference will be employed. for indicating like arts throughout the different views of the rawin s, in which:

igurel is a view in elevation with the boiler setting broken away, showing a flue cleaner system in accordance with my in vention, it being understood that in practice, the branch pi es and feed pipe are outside the boiler setting, as shown in Fig. 2. Fig. 2 is a horizontal sectional view of a boiler settin showing a plan of the cleaner system instal ed in position with relation to the tubes of a boiler of the well-known B and W type. Fig. 3 is a transverse vertical sectional view of a boiler and its setting such as shown in Fig. 1, and partly broken away illustrating the cleaner system in position, and showing the arrangement and disposition of the nozzles carried-by the distributing pipes with respect to the passageways betwecn adjacent rows of tubes. Fig. 4, is a detail view in plan partly broken away of one of the distributin pipes showing the inclination of the. disc arge nipples of the nozzles. Fig. 5 is a similar view of one of the distributing pipes showing the reverse disposition of the discharge nipples, and, Fig. 6 is a detail plan view of one of the discharge nozzles.

The embodiment of my invention herein shown for illustrative purposes, is of a flue cleaner system in accordance with my invention applied to a boiler of the wellknown B and W type.

When applied to a boiler of this type, the construction and arrangement of the nozzles interposed in the distributing pipes, enables me to arrange the distributing pipes at spaced points directly overlying the battery of tubes, thus overcoming and obviating any ditliculty in disposing of the distributing pipes among the tubes of the battery or boiler, and also obviating the necessity for supplemental jet or distributing pipes termmat-ing at or near the boiler setting as shown in Patent #984,919 above referred to, although it will be obvious that such supplemental jet or distributing pipescould be readily connected to the branch ipes of the system herein involved, should It so be desired.-

A flue cleaner of the type shown, embodies a feed pipe 10, one end of which is .in communication with a suitable steam pipe 11 havin a drain valve 12, the feed pipe being provi ed adjacent the supply pipe with a eut-oii valve 14. Thesald feed also preferably provided at or a ja'cent its other end with a drain valve :15, and con nected with the feed pipe at as many points as desired throughout "its length are upwardly extending branch pipes 16, each of which is provided at a suitable point,,preferably, near its connection with the feed pipe 10, with a shut-0E valve 1?. Elbow pipes as 18 connect the upper ends of the branch pipes 16 with the distributing pipes 19 arranged above the tubes 20 of the boiler. These distributing pipes are extended through one side wall of the boiler setting and may be journaled at their inner ends in the opposite side wall, but I prefer to sup port the pipes intermediate their inner'ends and the" installation wall by means of bracket clamps as 17 which are clamped on gether with the accumulation of ashes that has lodged in the said combustion chamber.

As above described generally, the system is similar to that shown, described and claimed in the above noted patents. In

-Patent #705,912 above referred to, certain oi the distributing pipes are shown as provided with handles a jacent their connectlug ends by means of which the distributing pipes .may be rotated on their axis. It freuently occurs, that the feed line 10 and the istributing pipes are located at such a in which the boiler is located, that ready access may not be had to the pi es for the purpose of rotatingthe same, an one of the objects of my invention, as heretofore stated, is to provide simple and efiective means for rotating the distributing pipes from the floor of the room in which the boiler is located. To this end, I provide on each of the distributing pipes 19, at .a point just outside of the front wall of the boiler setting, a

ipe 10 is normal sprocket or like wheel 23 over which oper- -ates an endless chain as 24, of such a length that the same will depend to or below the feed line 10, so that it can be readily reached by the, operator when desired.

Another of the objects of the present invention, as above stated, is theprovision of a specific form of nozzle, and the location of this nozzle with respect to the. boiler tubes or fiues, with the cleaning agent projected between the lines of the different rows of tubes, the angle of the discharge. nipple of spaces 26 which lie in a straight line ex tending at an angle of substantially throughout the depth of the battery of tubes or fiues, and in view of such arrangement' of the tubes in boilers of this type, I dispose the outlet nipples 27 of the nozzles at an angle of substantially 63 to the axis of the nozzle, and by this arrangement of the outlet nipple withrespect to the axis of the nozzle, it will beobserved that steam issuing from the nipple will be projected through the space 26 in such a manner that as the distributing pipe is rotated, the arc traversed increases so that the projected steam strikes the fiues more or less as the bottom fines of the battery are reached, the steam being-projected in the space cleaning the tines on opposite sides and its later contactwith the fiues direct serving to dislodge all soot which may have dropped thereon from'the fiues above. In order to keep the soot cleaned from the sides of the 'boiler setting, each distributing pipe is provided adjacent the ends with an opening as 29 projecting downwardly at dlrect right angles to the axis of the pipe, and cleanm the inner side of the boiler settin as well as the fiues which are located adjacent to such sides of the boiler setting.

As above stated, the invention resides particularly in the disposition of the nozzles and the arrangement of the discharge ni ples of said nozzles at an angle slighty greater than the angle of the spaces between adjacent rows of the tubes or fiues of the boiler, it being understood that the nozzles are arranged alternately on alternating distributing pipes, and are so disposed in the distributing pipes as may be required by the proximity of the bafile plates of the headers of the furnace with respect to the location of the distributing pipes, that is, the distributing pipe 19 located'adjacent to the header 30, Fig. 2, will have'the nipples 27 projected angularl toward the side wall opposite from whic the installation is made, the ipe 19 adjacent bafiie plate 31 will have t c nipples of the nozzles project toward the side wall through which the installation is made, while the nipples of the two intermediate pipes will alternate with these two pipes respectively. And these pipes in rotatlng will project the steam toward header 30 and baffle plate 31. The pipes as shown arranged between the baffle plate 31 and the header 32 and battles 31 and 33 will be similarly disposed, such arrangement providing for an oblique projection of the cleaning agent between all of the tubes or flues of the battery.

Having fully described my invention, what/I claim as new and desire to secure by Letters Patent is:-

1. In a flue cleaner system, a flue, a rotatably-mounted fluid distributing pipe arranged at an angle to said flue, a feed pipe therefor, a supply pipe to which the feed pipe is connected, and a plurality of nozzles interposed in the ipe and each provided with an outlet dlsposed obliquely to the axis of the pipe."
